Body SystemsBy: Drew CothranSkeletal SystemThe organs that make up your skeletal system are bones, cartilage, tendons, and ligaments.InteractionsNervous System - the vertebrae protect the spinal cord. Muscular System - the skeletal muscles are attached to the bone to give support when the muscles contract. Fun FactsOver a period of about seven years, each bone in our body is slowly replaced until it is a new bone. 1 out of every 20 people in the world have an extra rib. Over half the bones of your body are found in your hands and feet.

Muscular SystemThe main function of the muscular system is to give the body the ability to move.The main organs in the muscular system are smooth muscle, cardiac muscle, and skeletal muscle.The muscular system interacts with the respiratory system because the diaphragm is what enables the lung to inflate and deflate. The muscular system also interacts with the digestive system because it helps you swallow.Your eye muscles are the most active muscle, moving more than 100,000 times per day. There are 650 skeletal muscles in your body. 30 of those 650 are used to make all sorts of facial expressions.Smooth Muscle- Smooth muscle is found in the internal organs and along the digestive tract. Smooth muscles are under involuntary control and are controlled automatically by the nervous system. Smooth muscles are involved in functions such as digestion, bladder control and breathing.Cardiac Muscle- Cardiac muscle is only found in the heart. This type of muscle is involuntary, and it has properties of both smooth and skeletal muscle. Cardiac muscle can stretch like smooth muscle and can contract like skeletal muscle. Cardiac muscles contract in an organized manner and regulate the beating of the heart.Skeletal Muscle- Skeletal muscle, also called striated muscle, is usually attached to the skeleton and is usually under voluntary control.Circulatory SystemThe main function of the circulatory system is to pump the blood all around the body.The organs are the heart, blood, and blood vessels. Also, the lungs and brain are a big part of the circulatory system, and veins, arteries, and capillaries are a part of the system even though they are not always considered organs.The circulatory system interacts with the muscular system when they give oxygen to the muscles. The circulatory system also interacts with the respiratory system when oxygen from the lungs is pumped around by the heart.About 8 million blood cells die in the human body every second, and the same number are born each second. Red blood cells make approximately 250,000 round trips of the body before returning to the bone marrow, where they were born, to die. The heart beats around 3 billion times in the average person's life. Digestive SystemThe main function of the digestive system is to break down the food we eat into smaller parts so the body can use them to provide energy and build cells.The main organs in the digestive system are the mouth, pharynx, esophagus, stomach, small intestine, colon, rectum and anus. Also, the tongue, pancreas, liver, gallbladder, and the glands in the mouth that make saliva are accessory digestive organs, which are organs that help with digestion but are not part of the digestive tract. InteractionsThe respiratory system provides oxygen so the digestive system can digest your food.The nervous system receives energy for the brain for the thinking and controlling of the other systems.The liver is the largest organ in the body and performs more than 500 functions. Your stomach has hydrochloric acid in it, which is the same stuff that is in toilet bowl cleaner. In the mouth, food is cooled or warmed to a more suitable temperature.Respiratory SystemThe primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body.The organs in the respiratory system are the nose, mouth, pharynx, larynx, trachea, bronchi, alveoli, lungs, and the diaphragm. InteractionsCirculatory system when the respiratory system provides oxygen for the blood.Muscular system when the respiratory system removes the water and carbon dioxide that muscle cells produce as a waste product.The right lung is slightly larger than the left. Hairs in the nose help clean and warm the air we breathe. The surface area of the lungs is about the same size as a tennis court.Excretory SystemThe excretory system's main function is to remove waste and foreign substances from your blood.The organs that make up the excretory system are the kidneys, liver, gall bladder, small intestine, colon, skin, lungs, ureter, urinary bladder, urethra, bile, and eccrine glands. InteractionsIt interacts with the respiratory system because the lungs help remove waste gasses.It interacts with the endocrine system when the glands help remove sweat and wastes.The left kidney is higher than the right kidney. The average person urinates 7,850,000,000,000 gallons of liquid in his/her lifetime. The whole intestine is about seven and a half meters long.Nervous SystemThe main function of the nervous system is to regulate and control the body and to communicate to the body.The nervous system consists of the brain, spinal cord, nerves, and ganglia. InteractionsRespiratory System - it provides oxygen to the brain to think.Skeletal System - provides protection to the brain and spinal cord.There are lots of branches off of the main nervous system Central Nervous System - the control center of the body Peripheral Nervous System - connects the central nervous system to the limbs and bones.Somatic Nervous System - a division of the peripheral nervous system that stimulates the skeletal muscles.Autonomic Nervous System - a division of the peripheral nervous system that controls involuntary actions such as heartbeat and digestion.Sympathetic Nervous System - a division of the autonomic nervous system that forms the body's "fight or flight" response to stress, danger, excitement, exercise, emotions, and embarrassment. It also releases adrenaline and other stress hormones and increases respiration and heart rate.Parasympathetic Nervous System - a division of the autonomic nervous system that forms the body's "rest and digest" response when the body is relaxed, resting, or feeding.Enteric Nervous System - a division of the autonomic nervous system that is responsible for regulating digestion and the functions of the digestive organs.Immune SystemThe left side of your brain controls the right side of your body and vice versa. The spinal cord is less than two feet long and its diameter is the same as an index finger. There are 100 billion neurons in the brain.The main function of the immune system is to protect your body from diseases and infections.The main organs are the thymus, spleen, and lymph nodes. InteractionsCirculatory System - immune cells travel through the bloodstream.Integumentary System - skin helps prevent too many germs from entering the body.Fever and inflammation are signs that your body is doing its job. Laughter helps your immune system function better by reducing stress. Under five hours of sleep is linked to weaker immune systems. Functionssupport the bodyprotect the body
